Sometimes tapping the DISPLAY button in the notification panel after a map download has completed is ignored. It doesn't seem to be just a matter of waiting longer for the map to be displayed as sometimes it works, sometimes not.
As I see, tap on this button should display MapManager screen and also hide this dialog. For you, nothing happen, event dialog does not close?
Correct. Sometimes it worked, sometimes not. I did a few tests to be sure. There shouldn't have been any background task hogging the CPU but I can't be sure. It's not a big issue as rarely performed, but thought I should at least report it.
